PPT- Projectile Motion Notes

A projectile is an object upon which the only force acting is gravity An object dropped from rest is a projectile provided that the influence of air resistance is negligible   An object that is thrown vertically upward is also a projectile provided that the influence of air resistance is negligible . &. Lab Activity. Force (. F. ). : strength or power applied upon an object.. F = mass * acceleration. Definitions. Mass (. m. ). : the quantity of matter (atoms/particles) in the object. Gravity (. :. Place on Your Desk:. *Calculator & Protractor. 1) . Which instrument can we use in the lab to measure force (Newton's)?. . . . . . . Agenda. Warm-Up . 5 min. Vocab. Words . 10 min. What is Projectile motion?. . Projectile. . motion refers to the motion of an object projected into . the . air at an angle. .. A . projectile . has a single force that acts upon it - the force of . 2D Motion. Moving Motion Forward. Velocity, Displacement and Acceleration are VECTORS. Vectors have magnitude AND direction. So far, direction has been positive and negative. Motion with Vectors. Motion concepts combine with Vector concepts to allow us to represent motion in multiple directions simultaneously. Ideal Projectile Motion. Ideal Projectile Motion. What do we mean by the word “ideal” here?. T. he projectile behaves like a particle moving in a. vertical coordinate plane.. The only force acting on the projectile during its. Derivation of the Projectile Equations Vx 0 -gt 0 h=v2 2= V02+ 2ax0 = V02+ 2ax0 = V02+ 2ah-V2= h 2a02= h 2gh=v2 T=2V v = v0t = v/at = 2v/gT = 2V0 R=V2 V0R=V2 x = (V0x = vtV=VX = (V0 )t a = 0 case. no acceleration  velocity is constant  v = v. i. position vs. time  . x. f. = x . i. + v t,. x. i. is the starting . position, . x. f. is the ending position. acceleration = a = constant. Tennis ball. Golf ball. Football. Softball. Soccer ball. Bullet. Hockey puck. Basketball. Volleyball. Arrow. Shot put. Javelin. These are all examples of things that are . projected. , then go off under the . What is a projectile?. A body in free fall that is subject only to the forces of gravity and air resistance. Motion of bodies flung into the air. Occurs in many activities, such as baseball, diving, figure skating, basketball, golf, and volleyball. Physics. Coach Taylor. Broad Run High School 2010-2011. Objectives. Recognize that the vertical and horizontal motions of a projectile are independent.. Relate the height, time in the air, and initial vertical velocity of a projectile using its vertical motion, then determine the range.. MAT 493. Definition. Projectile Motion is defined as the motion of an object near the earth’s surface. . ‘Near’ .  Gravity extremely influential to the trajectory of an object. history. Aristotle – projectiles pushed along by some external force that was transmitted through the air called “impetus”. Analyze the free-flight motion of a projectile.. In-Class Activities:. Check .

Problem Solving. 7-2 Projectile Motion Independence of Motion in 2-D Projectile is an object that has been given an intial thrust (ignore air resistance) Football, Bullet, Baseball Moves through the air under the force of gravity Problems will be solvable using the equations of uniform acceleration. . .  . Projectile motion. This section is devoted to understanding the motion of projectiles. A projectile is an object upon which the only force acting is gravity.
